Genesis 12 · a question people ask
Did Abram lie about Sarai? And why isn't he punished?
Abram asks Sarai to say she is his sister (12:13). Later Abraham says she really is his half-sister: "the daughter of my father, but not the daughter of my mother" (20:12). The text doesn't state a verdict on Abram. It reports that the LORD strikes Pharaoh's house "because of Sarai" (12:17) and that Pharaoh rebukes Abram (12:18-19). Protestants read it two ways.
How Christians read it
Where Christians differ, Favor sets out the main views side by side and doesn't pick one.
A failure of faith
Abram, expecting to be killed (12:12), used a half-truth to deceive, and Sarai was taken into Pharaoh's house (12:15). The outsider, Pharaoh, is the one who speaks the rebuke: "What is this that you have done to me?" (12:18). God protects Sarai in spite of Abram (12:17).

A half-truth under threat
Abraham later says Sarai was his half-sister, and that they had agreed to say this wherever they went (20:12-13), so his words were true as far as they went, spoken to save his life among strangers (12:12). The text records the danger and God's protection without saying more about Abram's choice.
